But Dr Oktay Vural, Minister of Transport and Communications, insists the measures are not intended to stiffle sites.

"There are no restrictions. It is only that there have been several things which have been forbidden by the law," he said.

"So if these actions were taken through the internet, then the regulations will cover for those actions only. We cannot be an eye in the chatrooms; that is not the aim of that law.

"Let's see what happens. I don't think it will affect the internet. I think time will show the truth," he said.

Media controls

The new law puts the internet under the control of Turkey's Supreme Radio and Television Board.

According to Savas Unsal, that opens the door to the internet facing the similar restrictions as the rest of the country's media.

"A judge can tell you to bring a copy of your website whenever you update it to be approved by the local authorities," he said.

The law is unclear what it actually covers. According to Fikret Ilkiz, media lawyer for the Turkish daily newspaper, Cumhuriyet, internet providers could be liable for prosecution for anything written, even in chatrooms.

He also argues that the notion of "lying news" is too ambiguous.

"The biggest problem is that the law is very unclear. The law forbids fake or lie news. But what is this?" he asked.

"The law doesn't define what it is. It just says it's forbidden. And this could apply to chatrooms.

"The way the law is now, it will be defined by many court cases. For now, there is great uncertainty. No one knows what is legal and what is not. It is chaos."

'Ambiguous law'

Reaching a definition of the law by court cases could well be an expensive process for internet providers and users, with fines of up to $195,000 for each offence.

But some critics of the law argue it is deliberately ambiguous. Much of Turkey's legislation governing the control of the media is characterised by catch all phrases.

The internet until now has been largely exempt from such legislation. Such freedom has allowed it to become a powerful forum for criticising politicians.

Many journalists publish articles on the internet which neither television nor newspapers dare print, due in part to existing legislation.

The European Union, which Turkey aspires to join, has strongly condemned such legislation. This latest law has also drawn the ire of the EU, with officials calling for its repeal.

That could well happen because Turkey's President Ahmet Necdet Sezer has sent the law to the Constitutional Court, accusing it of breaching the constitution.

The court could take up to a year to make a ruling. In the meantime, the law remains in force.

Internet slowdown

The uncertainty created by the new legislation could prove most damaging of all to Turkey.
